- Control Panel

5. 

Bring the engine to full throttle using the 

Throttle Override switch (8) (toggle the 

switch up).

6. 

Enable to Auto-Brake release system by 

toggling the Auto Brake Switch up.  The 

Brake icon on the display will go from 

solid Red to alternating between Red and 

Green.  The Brake Icon will change to solid 

Green when the FNR (12) is moved out 

of the neutral position indicating that the 

brake release valve is energized.

7. 

Move the FNR (12) to F so the machine 

can be driven onto the trailer.

8. 

Slowly increase the setting on the Paver 

Speed Control Knob (14) until the paver 

starts moving. It is safer to use a slow 

speed while loading or unloading.

9. 

Watch the area at the rear of the tractor to 

be sure that components do not drag on 

the ground.

10. 

Back the machine off the trailer.

Preparation for Transport

Do not set the screed on nails, rivets, or bolts. 

These can cause damage to the screed bottom.
Chaining directly to the screed, truck hook, or tow 

arms could damage the equipment. When chain-

ing the machine to the trailer, all chains should be 

secured to the machine frame only.

NOTE:

 Both front and rear pair of cables/chains 

must be of equal length so that the machine s rais-

es evenly from side-to-side.

1. 

Load the machine onto the trailer or truck.

Figure 5.4 

- Screed On Blocks

2. 

Lower the screed onto blocks at each end 

and in the center of the screed.
